Electronics and optoelectronics with carbon nanotubes
Abstract
Various new discoveries in single-walled carbon nanotube (SWCNT) which have proven the most useful structure for electronic applications are presented. IBM is evaluating the potential of carbon nanotube as the basis of a future nanoelectronics technology. Several types of devices can be made using SWCNT instead of conventional semiconductor like silicon. SWCNT, which are one-dimensional systems, do not allow small-angle scattering of electrons or holes by defects or phonons that occurs in a three-dimensional system because carriers in them have only two directions of propagation forward or backward. With respect to FET, nanotubes do not have surface dangling bonds, as silicon does.
